This invention relates to means-for distributing and mixing liquids.

The primary object of my invention is an improved means, whereby liquid supplied by a con- 5 duit can be divided into two portions, adapted to being varied in very accurate proportion within predetermined limits, at a ratio from between 1:0 and :1.

Another object of my invention is a device,

0 including the aforesaid improved distributing means, whereby liquid supplied by two conduits can be evenly mixed in accurately variable proportions.

With these and other objects in view, my invention consists in the provisionin combination with a device for distributing a liquid with a distributor mounted vertically below the same, of a substantially horizontal conduit for supplying the liquid to be distributed and having its bottom provided with a longitudinal series of spaced substantially longitudinal slots, and having said distributor mounted for and capable of lengthwise movement relative to the series of slots and composed of pairs of adjacent transverse chutes arranged side by side longitudinally to said series each pair of corresponding to a slot and the chutes of each pair sloping downwardly, one towards the left and the other towards the right of the conduit, the total width of each pair of chutes as measured in the longitudinal direction of the conduit exceeding the length-of the corresponding slot measured in the same direction.

Other features of my invention will appear from the following description of some practical 35 embodiments and from the drawings, in which:

Fig. 2 is a vertical longitudinal sectional view along the line 11-11 in Fig. 1,

Fig. 5 is a cross sectional view along the line V-V in Fig. 4,

Fig. 7 is a plan sectional view along the line VIIVII in Fig. 6, and

Fig. 8 is a plan sectional view along the line VIIIVIII in Fig. 6,

Fig. 9 is a vertical cross section of a third em- 55 bodiment, and.

Fig. 10 is aplan sectional view along the line XX in Fig. 9.

Referring to Figs. 1-5, which illustrate my improved distributing means as applied to a distributing and mixing device, there are provided three parallel, horizontal conduits H, I2, l3 mounted side by side and in spaced relationship. Conduit is fed with liquid and conduits 82,13 are fed, by a common pipe M, with another liqquid, which liquids are to be mixed in variable proportions.

As particularly shown in Fig. -3, each conduit is provided, in its bottom, with a longitudinal series of four substantially longitudinal slots iii of equal lengths and spaced at intervals equal to said length. The axes of the slots make equal, relatively small acute angles with the axes of the conduits.

Mounted vertically below conduit 12 is a distributor, comprising an anglebar I6, secured to which are'eight transverse, inclined chutes I! located side by side and alternately sloping down to the right hand side and to the left hand side of the conduit. The width of each chute I1 is equal to the length of the slots l5 and of the intervals between two adjacent slots, the arrangement being such that each slot 8 5 cooperates with a pair of chutes ll sloping down in opposite directions. I

The distributor is adapted for lengthwise movement by means of a hand lever 88 (Fig. 2), mounted on a horizontal pivot l9 and having a pin and slot connection 20 with the angle bar 5. In the one extreme position of the distributor, the liquid discharged by each slot i5 is received entirely by the left hand side chute, in

the other extreme position it is received entirely by the right hand side chute, and in an intermediate position it is received partly by the right hand side, partly by the left hand side chute of the corresponding pair of chutes ll. between the amounts discharged by the one and by the other chute ll of each pair depends exclusively upon the adjustment of the distributor.

Conduits II and i3 do not cooperate with a distributor.

Vertically below the conduits H and I3 are narrow, elongated receptacles 2| and 22, respectively. Receptacle 2! receives the total amount of liquid discharged by conduit H in addition to a controllable proportion of the liquid discharged by conduit l2 into the distributor, whereas receptacle 22 receives the full amount of liquid discharged by conduit H in addition to the remain- The ratio 5 the receptacles 2i and 22.

f 4 der ottheliquid discharged by conduit is into the distributor.

Each conduit is provided with aslide valve'i locatedwithinthe conduit andprovided, outside 6 the conduit, with a handle 24, by means of which it can be moved in axial direction, special reference being had to Figs. 4 and 5. One lateral edge of said valve is saw teeth shaped and each saw tooth cooperates with one of the slots II in 10 such a manner that axial'movement of 'the slide valve results in a very gradual increase or decrease of the eflective sectional areas of the slots. In the extreme positions of the valve 23, the slots are fully open and fully closed, respectively.

Thus, by means of said slidegvalves the total amount of liquid discharged per unit of time by each of the conduits I I, -l2, l3 cansbe individually controlled as circumstances require.

Figs. 6-8 illustrate how, by combining two distributing means in accordance with my invention, a device is created whereby two liquids can be mixed in accurately variable proportions. To this end I provide two vertically spaced conduits 7.5, 26 fed by diil'erent liquids. Each conduit is provided with outlet slots IS in, the manner described hereinbeiore and cooperates with an individual slidable distributor I6, ii! in such a manner that the liquid from each of said conduits can be caused to flow, in a controlled proportion, into 80 the receptacles 2| and 22. The line A-A in Figs 7 and 8 serves to clearly show that the slots IS in conduit 25 are located in staggered relation to those in conduit 26, although this is not necessary. As to the two distributors, these may be arranged to be controllable individually, or in unison.

Figs. 9 and 10 show another embodiment of a mixing device, wherein two horizontally spaced conduits 21 and 28, led by different liquids and provided with outlet slots l5, cooperate with a common slidable distributor l6, H, the slots of stantially horizontal conduit for supplying the liquid to bedistributed having its bottom pro;
